Superior Waterproofing for Flat & Low-Slope Roofs
EPDM (Ethylene Propylene Diene Monomer) rubber roofing has been the go-to solution for low-slope and flat roofs for over 50 years. This synthetic rubber membrane provides exceptional waterproofing, UV resistance, and durability in all weather conditions — making it the ideal choice for porches, garages, additions, and commercial buildings across Southern New Hampshire.
At Compass Exteriors, we install EPDM systems in 60-mil thickness for maximum durability. Our installations follow manufacturer specifications precisely, ensuring proper adhesion, seam integrity, and flashing details that prevent leaks for decades.

- Flexibility: Remains pliable in extreme cold, ideal for New Hampshire winters
- UV Resistant: Won’t crack or deteriorate from sun exposure
- Cost-Effective: Lower installed cost than many alternatives
- Low Maintenance: Requires minimal upkeep over its lifespan
- Warranties: Available up to 30 years from the manufacturer
Our EPDM Installation
Proper EPDM installation is critical to long-term performance. Our process includes thorough deck preparation, proper insulation and drainage planning, fully adhered membrane application, and meticulous seam and flashing work. We also address drainage issues with tapered insulation systems when needed to prevent ponding water.
